AI might be 100x faster than me at writing code - but writing code is a tiny portion of the work I do. I need to understand the problem before I can write code. I need to understand my whole system. I need to test that my code really works - this is more than 50% of the work I do, and automated tests are not enough - too often the automated test doesn't model the real world in some unexpected way. I review code that others write. I answer technical questions for others. There is a lot of release work, mandatory training, and other overhead as well.

Writing code is what I expect a junior or mid level engineer to spend 20% of their time doing. By the time you reach senior engineer it should be less (though when you write code you are faster and so might write more code despite spending less time on it).

I can tell you, with absolute certainty, that before AI ~0 junior/mid level devs spent just 20% of their time programming. At least not at tech companies

My experience is very different. A junior should be spending >90% of their time coding, a mid level about 75% and a senior about the same. It only really splits after that point. But the senior spending 25% more time on the wrong thing is worse than than them spending 25% less time on the right thing.

It’s only when you get to “lead” (as in people manager) or staff (as in tech unblocked) you should spend the rest of your time improving the productivity of someone who spends more of their time coding than you do.
